Running Windows 7 64bit, I have a ton of MP3 audio files I would like to crop the same amount of seconds from the beginning of the audio, is there a Free application that can accomplish this? If no free applications please recommend others.

EDIT: I need something with a gui, no command line software if possible.

Let me guess: trim the intro music off of podcasts? –  Joel Coehoorn Dec 6 '10 at 5:13

Audacity will allow you to perform batch actions (called "chains") on any number of audio files. You'd load in the files, create a chain that trims the necessary number of seconds, and apply the chain to all the files you wish to affect.

Wow, I have used that software before, did not know it would do what I needed, thanks I will give it a try tomorrow. –  Moab Dec 6 '10 at 3:48
Unfortunately I don't have the hours to learn Audacity or chaining, I will however accept your answer, it can be done with Audacity. –  Moab Dec 11 '10 at 15:05
@geodave: you cannot do that with Audacity. None of the chain commands trim as wanted. –  simpatico Aug 12 '11 at 1:50
Audacity doesn't allow directly working with MP3's last I used it. –  Muhd Feb 14 '13 at 22:54

dBpoweramp Music Converter (dMC) has a nice GUI and can batch process audio files and has a DSP Effects plugin which includes the ability to trim a fixed amount of time from the beginning or end of a set of files in any of its supported formats. Unlike SoX and Audacity (the other answers), it looks like mp3 is one of the supported formats.

I'm sure SoX can handle this although I'd recommend some reading. It sounds like you're after the "trim" feature.

Thanks, I will check it out. –  Moab Dec 6 '10 at 3:08
Oh, command line software, thanks but no thanks. –  Moab Dec 6 '10 at 3:46
This generation has been babied way too much with GUIs. –  John T Dec 6 '10 at 4:27
Define "this generation" –  Moab Dec 7 '10 at 4:13
